Answer:
Step-by-step explanation:
6
1. X+2=3x-4
6=2x
x= 3
2. y= 8-x
8-x = 3x+4
4= 4x
X= 1
3. -2x +3(2x+7)=9
-2x + 6x + 21 = 9
4x = -12
x= -3
Answer:
best completes this argument
Step-by-step explanation:
Circumference of circle =
Where d is the diameter of circle
We are given that if equally sized central angles, each with a measure of n°, are drawn, the number of sectors that are formed will be equal to 
So, Number of sectors = 
The arc length of each sector is the circumference divided by the number of sectors

Diameter d = 2r (r = radius)

Option b is true
Hence
